说明：  本程序是用来进行运动估计的全搜索块匹配方法(This procedure is used for motion estimation of the full search block-matching method)

用MATLAB实现数字音频水印的嵌入和提取，即是在一段音频水印中嵌入二维图像。(Using MATLAB realization of digital audio watermark embedding and extraction, that is, over a period of two-dimensional audio watermark embedded image.)

The fisher iris data file in matlab (in case you do not have it). usually it comes with matlab and is called "fisheriris.mat" and can be read without specifying the path of the file.

共上载5个源码，其中c语言c_matrix为矩阵类，可以实现几十种矩阵运算；其它四个为matlab程序，用于生各种杂波的程序(Upload a total of 5 source code, in which c language for c_matrix matrices can be achieved dozens of matrix operations the other four for the matlab program for Health and a variety of procedures Clutter)

基本蚁群聚类算法及其改进算法[带Matlab源代码] 该算法，解决了不收敛的问题，聚类效果非常好（效果图如附件图片所示）。 改进的蚁群算法是基于遗传算法的改进，在基本遗传算法的基础之上，加入了变异因子， 产生变异，从而更快的收敛。 (The basic ant clustering algorithm and its improved algorithm with Matlab source code of the algorithm to solve the non-convergence problems, the clustering effect is very good (image such as shown in the attached images). Improved ant colony algorithm is a genetic algorithm-based improvements in the basic genetic algorithm based on the added factor of variation, mutation, and thus faster convergence.)
